Hi,

could you send your patches inline, instead of as an attachment? It
makes reviews easier. The workflow on your side is easier too, since you
only need to `git send-email` (available as git:send-email in guix).
It's fine if you prefer not to do this, though.

I'm not sure if audio.scm is the best place for a GUI toolkit. It might
be fine since audio plugins are the primary usecase, but I'm not sure.

Please run etc/indent-code.el on your packages.

Why are these propagated-inputs? I would've thought that these
dependencies get linked into the binary, so they don't need to propagate
to the user's profile.

Why the dependency on git? The package seems to build fine without it.

Same question as above.

That's quite blunt, and impenetrable for non-domain-experts. Is there
really nothing more you could say about the package? Perhaps expand the
acronym?

Consider using Texinfo's @acronym.
